There are are a couple of valuable tricks already in this toolkit:
1) a fix for NUnit (and others) to allow unit testing things which must run in STA mode.
2) a way to make your XAML data binding testable by tracing data binding warnings

Microformats are about enhancing the web, representing data in HTML and moving that data around. Oomph: A Microformats Toolkit is for web developers, designers and users, making it easier to create, consume, and style Microformats.

"The CCR and DSS Toolkit delivers delivers a set of .NET and Compact Framework class libraries and tools that enable developers to better deal with the inherent complexities in creating loosely-coupled concurrent and distributed applications."

design and build your application as a .NET client application, then assign the
portions of the application to run on the server and the client tiers late in
the development process. The compiler creates cross-browser JavaScript for the
client tier, web services for the server tier, and communication, serialization,
synchronization, security, and other boilerplate code to tie the tiers together.

Volta is to .Net what the Google Web Toolkit is to Java ... except it goes *way* further, because it lets you write a multi-tiered application as a rich-client app and then choose to have the client portion "compile" to HTML+Javascript ...

"You may want to give it a second look. Not just at distributed version control systems, but at the real role of version control in your creative toolkit. In this article, I'm going to introduce you to Git, my favorite DVCS, and hopefully show you why it is not only a better version control system than Subversion, but also a revolutionary way to think about how you get your work done."

SharpKit enables web development teams to take advantage of C# and Visual Studio benefits such as compile-time syntax verification, code-completion, XML documentation and refactoring. Many developers prefer this managed code environment versus the expensive and error-prone world of JavaScript programming.
